The class of InheritedVSPDisInfo and related codes are (virtually) not used. They looks used but not affect for the results. A patch is attached.

In I.7.3.8.5.2 Coding unit extension syntax, depth_dc_sign_flag is signaled when depth_dc_abs[x0+k][y0+j][i] is greater than 0 as follows:

dcNumSeg = DmmFlag[ x0 + k ][ y0 + j ] ? 2 : 1 if( depth_dc_flag[ x0 + k ][ y0 + j ] )

for( i = 0; i < dcNumSeg; i ++ ) {

depth_dc_abs[x0+k][y0+j][i] if(depth_dc_abs[x0+k][y0+j][i] >0)

depth_dc_sign_flag[x0+k][y0+j][i]

}

On the other hand,in HTM-12.0, it is signaled when the absolute value of DcOffset is greater than 0 as follows:

Void TDecSbac::xParseDimDeltaDC( Pel& rValDeltaDC, UInt uiNumSeg ) {

UInt absValDeltaDC = 0; xReadExGolombLevel( absValDeltaDC, m_cDdcDataSCModel.get(0, 0, 0) ); rValDeltaDC = (Pel)absValDeltaDC + ( uiNumSeg > 1 ? 0 : 1 ); ... if( rValDeltaDC != 0 ) {

UInt uiSign; m_pcTDecBinIf->decodeBinEP( uiSign );

} ...

}

Signaling condition for depth_dc_sign_flag in WD should be aligned with HTM-12.0 as follows:

for example

dcNumSeg = DmmFlag[ x0 + k ][ y0 + j ] ? 2 : 1 if( depth_dc_flag[ x0 + k ][ y0 + j ] )

for( i = 0; i < dcNumSeg; i ++ ) {

depth_dc_abs[x0+k][y0+j][i] if((depth_dc_abs[x0+k][y0+j][i] - dcNumseg + 2) >0) or if((depth_dc_abs[x0+k][y0+j][i] + (dcNumseg > 1 ? 0 : 1 ) >0)

depth_dc_sign_flag[x0+k][y0+j][i]

}

The 'SbW’ of the following sentence in subclause I.8.5.3.2.17 – When ( SbW + nSbH ) is equal to 12

should be replaced by 'nSbW'.
